piston question

[upnover]

I have a set of Cummins pistons that are marked 6223 on top but don't know much about them. Does anybody know if they would be good for performance, what injector spray angle, what compression are they etc.?
I did some searches on here with the number but nothing came up.They look to have a good size tapered dish like the marine version but I have not seen allot of diesel pistons to compare them to.

Thanks for any info.

not exactly sure, but from what i can find on google is they are a Naturally aspirated piston found mostly in Ag/Construction/Industrial type engines. No idea on the other specs.

like kino all i found is that they are a common replacement piston for the NA cummins motors in off road applications. its pretty much a standard piston for non turbo engines which is probably a 22:1 compression unlike the turbo ones which i believe are 18:1
